The fanfiction could show that the training by the dragons is a turning point for both Zuko and Katara. The dragons, being ancient and wise, could expose them to a whole new level of elemental power. Zuko could learn to control his fire in a more refined way, like using it for healing as well as for combat. Katara, on the other hand, might discover new forms of waterbending related to the spiritual aspect. They might also encounter other mystical creatures or places during their training, which would add more adventure and depth to the story. This could ultimately lead to a change in their relationship, from being somewhat at odds to being true friends and allies.
In this fanfiction, they might gain powerful new bending abilities. Zuko could further master his firebending, and Katara could learn unique waterbending techniques from the dragons. Maybe they'd also develop a deeper understanding of each other's cultures and overcome their past differences.
The training makes them more confident in their bending. Zuko becomes surer of his place as a firebender, and Katara gains more confidence in her waterbending skills.
One interesting plot development could be that through training with the dragons, Zuko and Katara start to understand each other's cultures better. As they learn the dragon - inspired bending techniques, they see how Fire Nation and Water Tribe elements can blend in unexpected ways. For example, Zuko might use water - like fluidity in his firebending, inspired by Katara's waterbending style. And Katara could incorporate the intense heat and energy of fire into her ice - making, creating a new form of waterbending that is more powerful.
In a fanfiction where Naruto is trained by dragons, his power would skyrocket. Dragons are known for their raw power and wisdom. Naruto could learn to harness the elements in ways he never thought possible. For example, he might learn to breathe fire like a dragon or use dragon - scale - like defenses. This training could also open up new storylines, like him having to protect the dragon realm from threats or using his new skills to face off against powerful enemies in the ninja world. His relationships with his friends and allies might also change as they see him in a new light with his dragon - trained powers.
They might discover new bending techniques. Since Zuko is a firebender and Katara a waterbender, they could exchange knowledge and learn from each other's bending styles during their travels.
Some fanfictions explore their role in rebuilding the world after the war. Zuko and Katara could be working together to restore balance between the nations. This kind of fanfiction often shows their leadership skills and how they complement each other.
For Zuko, the training might change his view on bending. Instead of seeing it as a tool for power or revenge, he starts to see it as a form of art, like the dragons do. This could make his firebending more refined and less aggressive. For Katara, she could become more confident in her abilities. The dragons' power and wisdom might inspire her to be more creative with her waterbending, perhaps finding new ways to heal or attack.
It would likely become more complex. They would have to rely on each other more as parents. Their love might deepen as they share the experience of raising a child together.
Their relationship would likely become more intimate and complex. They would have to rely on each other more, sharing a bond that goes beyond their previous friendship or alliance. Zuko would probably become more protective of Katara, and Katara would trust Zuko with her vulnerability during pregnancy.
Sokka would be protective of his sister. He would probably start by trying to negotiate with Zuko's side to call off the marriage. If that doesn't work, he might come up with a plan to rescue Katara, perhaps enlisting the help of their other friends and allies.
In fanfiction, Zuko and Katara's married life could be full of adventure. They might travel the world together, using their unique bending abilities to help people in different kingdoms. Their relationship would be a blend of passion and mutual respect, with Zuko's leadership skills and Katara's kind heart making them a power couple in the Avatar world.
